As shown in the illustration below, the PCD4.C225 is connected to the PCD2 via a
PCD2.K100/K110/K120 extension cable.
Using standard PCD4.C220 or PCD4.C260 bus modules, up to 6 additional module
sockets can be attached to the right-hand side of the PCD4.C225 coupling bus
module (making a total of 8 PCD4 sockets).
